My research areas span Quantitative Conservation Ecology and Probabilistic Risk Assessment. I apply population models, mathematical treatments of uncertainty and decision-making techniques to address conservation and wildlife management issues and ecological risk assessment. My research activities are broad and interdisciplinary and include: treatments of uncertainty in conservation, ecology and risk assessment; population viability analysis of endangered and threatened species; formal decision making for conservation management.

Students and post-docs interested in these areas are welcome to join my laboratory. I am affiliated with the Ecology graduate group within EEOB .
